Title: Improvements relating to the cooling of electric bus-bars
Inventor: COLLONGE PERRY J
IPC: H02G5/10
Filed: 1957-07-25
Abstract: 818,029. Cooling bus-bars. I-T-E CIRCUIT BREAKER CO. July 25, 1957, No. 23637/57. Class 36. Coolant such as air is fed from a blower 51 and ducts 52, 53 into a hollow conductor 20 connecting a generator 31 to a transformer 38. Some of the air passes towards the transformer and returns between the conductor and a housing 30 to a return duct 60 feeding the blower via a heat exchanger 73 while a baffle 62 causes the air flowing in the conductor towards the generator to flow first in one half the conductor then along the other side of baffle to apertures 69 in the conductor whence it joins the remainder of the air flowing back from casing 30 to the blower. The conductor is supported in the casing 30 by insulators arranged at intervals and a barrier 61 surrounds the conductor near the generator terminals to prevent leakage of hydrogen from the generator into the air system. An increased cooling effect may be obtained by giving the conductor an external absorbent covering on to which water is sprayed.

Patent GB-239968-A (GB)
Abstract: 239,968. British Lighting & Ignition Co., Ltd., and Hutton, J. C. July 15, 1924. Mechanical interrupters for ignition circuits of internal-combustion engines comprising a flat blade spring fixed at one end and carrying a contact at the free end have a strengthening part extending from the contact over substantially the whole surface of the spring to a point approximately midway between the two ends at which the spring is engaged by the deviating cam. As shown in Fig. 1 the spring blade C carries a contact B at its free end, where it is strengthened by a metal strip D<1>, one end of which is bent up at D<1> to form a heel-piece which is struck by the rotating cam A. A bent metal strip E secured at the fixed end limits the outward movement of the blade C, the blade C being made wider at this end than at the free end. A similarly constructed blade for use with a face cam is shown in Fig. 4, the heel D being arranged to take the blow from the cam and radial edge. An alternative strengthening means for the blade is by embossing the part to be strengthened to a dishshaped section. A felt pad may be arranged near the spring to damp uncontrolled oscillations, and may supply lubricant to the friction-surfaces.

Abstract: 194,329. Midgley, A. H. Sept. 10, 1921. Switches, locking; flexible-pull actuation; handles.-In electric switches for the electric circuits of motor vehicles, a key n operates the ignition circuit by means of a contact bridge o, and a handle k the lighting and starting circuits, the former by a contact bridge i and the latter either directly or indirectly through a Bowden or like wire l. The key n operates a barrel lock m so that the switch o is rendered inoperative until unlocked, and locking means are provided to prevent movement of the handle k to a different position unless the lock m is open. These means comprise a pin or bolt x engaging a series of recesses u containing balls w in a sleeve t of the handle k. This pin x is locked until the key is inserted in the lock m and rotated to bring the recess z into the position shown in Fig. 2, where the pin can ride over the parts between the recesses u when the handle is rotated. A groove v in the part r of the handle similarly prevents axial movement of the handle to actuate the starting switch.

Title: Improvements in cracking hydrocarbons
IPC: C07C11/02
Filed: 1957-07-31
Abstract: Gaseous olefines, particularly ethylene and propylene, are produced by cracking oils in a process wherein the starting material is separated into a distillate amounting to 20-70 weight per cent of the initial material and a distillation residue, the distillation residue is cracked at 630-800 DEG  C. under coke-forming conditions in a fluidized layer of granular solids, the outer shells of which are formed of coke produced in the process and the distillate is cracked at a temperature of 720-900 DEG  C. and at least 20 DEG  C. higher than in the coking process, on heat-resisting non-oxidizing and/or carbonaceous solids.  The starting material can be mineral oil, shale oil, tar or their fractions or cracking or destructive hydrogenation products; the separation can be carried out if desired under reduced pressure and/or while supplying steam.  If a mineral oil is the initial material the distillate may boil between 150 DEG  and 375 DEG C.  The distillate residue may be cracked using reaction times of 0.5 to 10 seconds.  The fluidized solid must be withdrawn as necessary to maintain the desired height of solids. Also to maintain a desired grain size a certain amount of solid from an extraneous source may be added, withdrawing an equivalent amount.  Heat can be supplied by heating the solids in a combustion chamber e.g. by burning part of the fuel oil boiling above 300 DEG  C. formed in the cracking; or autothermally by introducing oxygen and steam into the reaction chamber when it may be necessary to return cracked oil residue boiling above 250 DEG  C. and containing carbon black to the reaction chamber to maintain the rate of coke formation above the rate of coke burning.  The solids used in this process or the cracking of the distillate may be natural or synthetic inert substances containing oxides of magnesium, silicon and/or aluminium or carbonaceous material. Coke produced in the cracking of the distillation residue may be used in the cracking of the distillate.  The distillate is cracked using reaction times of 0.1 to 2 seconds.  Heat may be supplied by heating the solids in a separate combustion chamber to 800-1200 DEG  C. by burning carbon deposits and further fuels such as fuel oil boiling above 150 DEG  C. produced in the other process; or by introducing oxygen or air into the reaction chamber in which case coke formed in the other process is used as fuel and as the solid. In both processes atmospheric or higher, e.g. 2-30 atmospheres pressures can be used.

[Also in Group XIII] Apparatus for burning, calcining, sintering, drying or preheating loose granular material, e.g. cement raw material, comprises vertical concentric casings of circular or polygonal shape defining an interspace charged from above with the loose material and closed by a bottom wall, discharge ports spaced around the foot of the inner casing opposite reciprocating rams disposed around the outer casing, and means for introducing hot air or hot gases into the interspace in counter-current to the charge material. Fig. 1 shows the invention applied to a shaft furnace in which the interspace formed between the outer casing a and the inner casing b is closed by a bottom wall d extending inwardly to form a central opening f through which discharged material falls into a shoot g leading into a cooler i having an air-permeable grate h and a discharge drum k. Combustion air introduced by the pipe m into the upper part of the shoot g above the plug of discharged material formed therein, enters the interspace through the discharge ports e or at varying heights in the shaft through valve controlled branches off a central pipe o. Additional air may be introduced, through pipes n into the casings containing the reciprocating rams c. Fig. 2 shows a drier and preheater of generally similar construction to the furnace shown in Fig. 1 attached to a rotary furnace s. The shaft is closed and charge material is distributed over the interspace by a rotary pocketed drum p and a rotary shoot r, hot gases from the furnace which enter the interspace at various heights as shown by the arrows being removed by an offtake r. The interspace cross-sectional area may be increased upwardly or downwardly. In a modification, Fig. 3 (not shown), the rams are disposed in the wall of the inner casing b, and the discharge ports in the outer casing a, the lower part of the apparatus being surrounded by a jacket which merges into a hopper connected to the rotary furnace s.
